Guys, no point changing your halogen bulbs.
I've used all those diamondvision, crystalvision from Phillips and the conclusion is, it's no better than the default bulbs (Halogen). Because the color is lighter (whiter), the illumination actually becomes worse off than before.
HID bulbs can be changed but in general the default is the best color for vision. 6000k looks better from the outside, but for driving purposes, it's actually not as bright/clear as compared to the default 4300k lights.
Btw, what the comfort push start is instead of a key ignition, it's just a slot where you push your key in to start the car. Like the normal push start button engine, you have to press the brakes to start the car.
Frankly, I actually find push-start button engine annoying. Because this means I have to get into the car, push the brakes and press the button just to start the engine compared to key start where I just open the door, slot the key in and turn and the car starts, I don't even need to get in the car. Usually this happens when the errand is longer than expected and you have passengers in the car, so you return back to start the car for them so that the air-conditioning runs.
Wonder what is the kelvin scale for your Passat? That look really bright. Bi-Xenon usually above 6000K?
